Rainbow Moonstone: The Dreamy “Moonstone” That’s Actually Labradorite

Rainbow Moonstone is a trade name—mineralogically, it’s white labradorite (plagioclase feldspar), not the orthoclase moonstone covered above. What makes it special is the labradorescence: on a transparent-to-white body, you’ll see blue, purple, and green flashes that shift as the stone rotates. It’s one of the most popular crystals for young women and spiritual practitioners alike.

Buying Guide

• Look for: Transparent body, vivid and mobile iridescence, large flash area. Full-spectrum flash commands a premium over single-color.
• Identification: Natural flash moves with angle; synthetics look static. Don’t confuse with opal—opal is softer (Mohs 5–6) and water-bearing.
